i installed kali linux on my laptop n5520 dell inspiron its not showing wifi connections in it.
The wifi on that laptop looks like it is a specific dell model adapter and driver set. It is entirely possible that the network drivers provided by linux are not compatible wit that specific wifi adapter.
This link appears to have a set of linux wireless drivers that may work with your set-up. Centrino N2230 driver.

Assuming you’re using the newer rolling Kali, there are a few things it could be and you could try.
1) Ensure the device even recognizes your network adapter is there. Easy way to do this is by typing airmon-ng into terminal. It should show the name (usually wlan0) on left and on right it will show the model. This information is helpful for diagnosing as well.
2) Sometimes the networking service and/or the network-manager service gets glitched up. Restart these by typing the following 4 commands in terminal in order –
service networking stop
service network-manager stop
service network-manager start
service networking start
3) A lot of laptops have wifi switches, either toggle switch on case, or a fn+key combo. Ensure the switch is turned on and/or the key combo is pressed and try again. An easy way to check this as well is using command rfkill list all. If it is software-blocked the command rfkill unblock all should fix that.
Hopefully one of these fixed your problem. If it still isn’t working, feel free to let me know and we can try additional steps to resolve it.
